Frequently Asked Questions
Will converting AVI to MP4 lose quality?
The conversion re-encodes the video, but at the default quality settings the difference is not visible for typical footage. MP4 with H.264 is the most compatible format there is — the small re-encode cost buys playback on every device.
My AVI is huge — will the MP4 be smaller?
Almost always, and often dramatically. AVI files typically carry old inefficient codecs; re-encoding to H.264 usually shrinks them severalfold at the same visual quality. For even smaller output, run the result through the compressor.
